I don’t know what smaller details there might be about the oracle information or other outside input things there are that people might complain about, but my impression is that it is a sound setup? The reason I say “impression” is because I’m not familiar with the details. I think all the details are publicly verifiable though.
It's true that I haven't studied DAI --- because I haven't felt any need to. I know how to buy currency that is every bit as stable as DAI and much more widely accepted and easily redeemable --- just buy USD.
Have you studied DAI? Are you sure that their algorithmic trading works the way they claim it does? How did you verify this?
Most "stablecoins" are built on trust of some sort at some level. Until someone audits them, you really have no idea if that trust is warranted.
